Subject: [PATCH v2 4/4] regulator: rpmh-regulator: Add RPMH regulator
support for Glymur
Add support for PMH0101/PMCX0102/PMH0110/PMH0104 PMIC voltage
regulators which are present on Glymur boards.
Introduce new LDOs & SMPSs under them (PMIC5 subtype 530 for
both).
For these new LDOs support a new optimum power mode(OPM). In
this mode LDO will automatically switch between high power mode
(HPM) and low power mode (LPM) based on the real-time LDO load
current. Its operation is analogous to SMPS AUTO mode.
